The truck version of the 12 bolt is very equal in strength to the 8.5" 10 bolt axle.

Hello, it has 2.73 gears, I want to get limited slip differential with 3.55 or 3.73. And was thinking I could get a complete rear end from a newer truck and swap it!

If your in market to swap one from newer truck I'd recommend 2014 amd newer chevy/gmc it has 3.73 gears, auto locker, disc brakes and best of all a 9.75 ring gear. It's way stronger than the 8.5 10 bolt.

You'd need to move spring and shock hangers but that's not a huge task
